MA-301
The MA-301 accepts a 50-pin Telco connector (Amphenol 57-30500
or equivalent, as shown in Figure 1.) One MA-301 Module Adapter
can be used to connect up to three RFL VF-5XP modules, for a total
of up to six voice channels. If you will be using more than one module
with the MA-301, they must be inserted into adjacent slots in the
9508. Ribbon cables are provided with the MA-301 to make
connections to it from the second and third module locations as
shown in Figure 2. This module adapter occupies one rear chassis
slot.
MA-301A
The MA-301A is used to isolate the VF-5XP from SWC type surges
sometimes present on 4-wire voice lines. This module adapter
occupies two rear chassis slots. A terminal strip is provided for hard
wire connections to the voice circuit for Channel 1 and Channel 2, as
shown in Figure 3. E&M signaling connections are not available
when using the MA-301A.
MA-301B
The MA-301B provides pluggable terminal block connections for a
single VF-5XP module. Audio and signaling connections are
available at the terminal block. No additional SWC or fast transient
protection is provided on this I/O. Refer to Figure 4 for panel view
and terminal connections. This module adapter occupies one rear
chassis slot.
MA-322
The MA-322 accepts a 50-pin Telco connector (Amphenol 57-30500
or equivalent, as shown in Figure 5.) One MA-322 Module Adapter
is used for each RFL VF-5XP module, and occupies two rear chassis
slots. The MA-322 is used to convert both of the 4-wire outputs
(Channel 1 and 2) from 4-wire to 2-wire. The impedance is 600
Ohms, the frequency response is
±
2dB from 200Hz to 3000Hz, and
the transformer loss (hybrid loss) is
≅
4.0dB. Refer to Application
Note No.14 in the IMUX 2000 Instruction Manual for additional
information on using this I/O.
MA-324
The MA-324 accepts a 50-pin Telco connector (Amphenol 57-30500
or equivalent, as shown in Figure 5.) One MA-324 Module Adapter
is used for each RFL VF-5XP module and occupies two rear chassis
slots. The MA-324 is used to convert one of the 4-wire outputs
(Channel 1) from 4-wire to 2-wire. The other 4-wireoutput (Channel
2) remains 4-wire. The impedance is 600 Ohms, the frequency
response is
±
2dB from 200Hz to 3000Hz, and the transformer loss
(hybrid loss) is
≅
4.0dB. Refer to Application Note No.14 in the
IMUX 2000 Instruction Manual for additional information on using
this I/O.
